Continuing on the vertical stabilizer

Assembly: vertical stabilizer

Manual ref: VS2 and E6

Today we drilled al the necessary holes for the vertical stabilizer to 5.8mm which corresponds with the outer diameter of the supplied m4 rivnuts and gives a smooth press fit. We drilled 6 mm holes in the vertical stabilizer angle (VS-ANG-001) left and right to fit the rivnuts through with play.

We also drilled some holes in the vertical stabilizer rear spar to 4.5mm for the m4 bolts to fit through with a bit of play.

After drilling we noticed a couple of scratches, this probably happened by the aluminium bures that were stuck in the wood which we used to clamp the profiles.Therefore we polished and primed the parts again that were a bit scratched..

We did not yet install the rivnuts due to the fact that we want to use loctite (277/272) to give an extra secure rivnut placement as recommended by Craig's Sling 4 Build Log. We ordered the loctite, this will however not arrive in the coming few days, so we will continue with the elevator and put the vertical stabilizer on hold for now.

To work ahead a bit we primed al the parts for the elevator. Most parts were already deburred and cleaned. The remaining parts were deburred and cleaned today. All of the parts were primed and are now drying.

When we are waiting for the loctite to arive when can already start building the elevator tomorrow.

An mistake was made today with the cleaning of already allodined parts. All hinge brackets except for one should not have been cleaned, however we did anyway. To solve this we also primed these parts were they used to be alodined, we hope this does not cause any big problems but to make sure we will contact the manufacturer (Sling) about this issue.
